feat(ecs): wildlife_near / wildlife_near_of into the caller's list, wildlife_alive_of

Browse source 
The living animals around a point from the grid (a rare species from its own list), into a list
the caller keeps in its own state, so a frame's proximity question walks the cells it covers
rather than every animal ever made. wildlife_alive_of is the species index's count.
